Strength
Strength is the trainable base: the bench, squat, deadlift and pull-up numbers people chase, and the programming that actually moves them. The mechanism is one sentence from Harvard Health — training “challenges muscles, damaging its fibers, which the body then repairs” — and everything in these 8 guides is about applying that sentence deliberately: load, technique, recovery, and testing without ego.
What the medical literature adds to a barbell
Two boring-but-valuable sentences, straight from Harvard Health’s starter guidance.
First: “always check with your doctor before embarking on any strength training routine” — blanket advice, more serious with existing conditions. Second, for the first reps especially, their recommendation is human: investing in sessions with a “licensed and credentialed personal trainer” who can design a personalized program. That is also, not incidentally, exactly what a good training app is trying to replace at scale — with the honest caveat that an app cannot see your form; the technique guides below are written to compensate as far as text can.
The complete strength library
System first, then the four classic lifts, then the measurement layer. Percentages, rep schemes and benchmark tables live inside each guide with their own sources — the index carries none.
Frequently asked questions
Today’s PAA set, answered with what the opened literature supports — and with named refusals where it doesn’t.
What is the 3-3-3 rule for strength training?
We found no randomized strength protocol by that name. The only researched “3-3-3” is interval walking — three minutes brisk alternating with three easy — whose 2007 trial measured leg strength, aerobic capacity and blood pressure in adults around age 63, not bench press. Online the label is used inconsistently; treat any rep scheme borrowing the name as marketing unless it cites its study.
What are some good strength training guides?
The honest local answer: the eight above, chosen so each covers one decision (programming, a specific lift, a test, a standard) rather than overlapping listicles. How to judge any strength guide elsewhere: does it name its sources, distinguish novice from trained lifters, and state when not to test maxes?
What are the 7 types of strength? / The 5 basic strength trainings?
Counted lists like “7 types” or “5 basics” vary by coach and site — there is no settled taxonomy in the opened literature to cite — so this page doesn’t publish one. What the guides do share: compound movement patterns, progressive load, technique work and recovery; each term is defined where it’s used.
